一种副枪PLC控制通讯网络系统
摘要：
本实用新型提供一种副枪PLC控制通讯网络系统，包括PLC及与PLC相连的多条并行的DP总线分支。所述的多条并行的DP总线分支上均设置有光电转换器，所述的PLC为西门子系列PLC，通过西门子的PROFIBUS-DP通讯电缆与每条DP总线分支上的光电转换器的电缆入口相连，每个光电转换器的出口通过通讯光纤连接各自的并行DP总线分支。所述多条并行的DP总线分支的其中至少一条总线分支上连接有西门子ET200分布式IO；1)采用多路DP结合光电转换器的网络检测功能，减少网络故障率；2)采用西门子ET200分布式IO解决不具备DP功能的分散电气元件与DP总线的连接问题。3)采用带DP通讯功能的气动阀体站(NORGREN型号VS261000026)解决机械手气动阀体过多，控制过多布线混乱的问题。
摘要（英）：

The utility model provides a sublance PLC control communication network system. The sublance PLC control communication network system comprises a PLC and a plurality of parallel DP bus branches connected with the PLC. The plurality of parallel DP bus branches are respectively provided with a photoelectric converter. The PLC is a Siemens series PLC, and is connected with a cable inlet of the photoelectric converter on each DP bus branch through a PROFIBUS-DP communication cable of the Siemens, and an outlet of each photoelectric converter is connected with the respective parallel DP bus branchthrough a communication optical fiber. At least one bus branch of the plurality of parallel DP bus branches is connected with a Siemens ET200 distributed IO. The method comprises the following steps:1) reducing the network failure rate by adopting a network detection function of combining multi-path DP with a photoelectric converter; and 2) the Siemens ET200 distributed IO is adopted to solve theconnection problem of the distributed electrical elements without the DP function and the DP bus. And 3) a pneumatic valve body station (NORGREN model VS261000026) with a DP communication function isadopted to solve the problems of excessive pneumatic valve bodies of the manipulator, excessive control and disordered wiring.
